How to calc right ascension and declination of the vernal and autumnal equinox for an observer at 46deg N Lat.?

Also, similarly how do you determine the altitude and azimuth of the zenith and north pole for an observer at 50deg N latitude?

  1. Vernal Equinox–0h RA, 0* Dec
    Autumnal equinox–12h RA, 0* Dec
    Zenith for 50* Lat–90* altitude, 0* azimuth or any other you wish, as it has no meaning for zenith.
    North Celestial Pole altitude for 50* Lat–50*, Azimuth–0*

  2. The only RA and Dec for the vernal equinox is 0h and 0 degrees.
    The only RA and Dec for the autumnal equinox is 12h and 0 degrees.
    The altitude of everybody’s zenith is 90 degrees, and the azimuth of anybody’s zenith is undefined.
